Play the Best Online Slots

We know you want to play the best online slots so we have set up Online-Slots.casino to help you find them. Our online slot review pages contain slot reviews of the latest and best online slots. Each slot review also allows you to play the slot for free allowing you to ‘test drive’ each slot and find your favourite.

Once you’ve found an online slot you would like to play you’ll need to visit our online casinos pages where you’ll find the best online slot sites to play at. Our online casino reviews contain details on the company behind the slots site plus information on the slots games available to play and any bonuses being offered.

Each online casino offers various types of sign up or welcome bonus, each one slightly different from the next. The online slot bonuses page details what bonus each slots site is offering as well as information on what the bonuses mean.

Looking to get some free spins on your favourite slot then our online slot free spins page gives details of online slot sites giving them away and details of what free spins are and how to use them.

Each online slot has a slot payout percentage but what does that mean and how does it affect you. Ever wondered why you prefer a certain look and feel of an online slot, that could be down to its slot variance.

How do we know that the online slots are fair and safe? Well every online slot site reviewed here has an online casino licence from the British Gambling Commission ensuring that they are regularly tested for fairness, security and a high level of customer service.

New Online Slots

The latest online slots to hit the casinos. These are new online slots that we have just reviewed:

New to play at William Hill Slots is Zhao Cai Jin Bao Jackpot Slot which means ‘we wish you wealth and success’. It’s a 5 reel 9 payline progressive jackpot slot that is linked to Playtech’s whopping Dragon Jackpot prize. Also new at William Hill Casino is Geisha Story Jackpot Slot which is a 5 reel 15 payline slot again linked to Playtech’s Dragon Mystery Progressive Jackpot.

New at BGO Vegas Slots is the Space Invaders Slot from Playtech Slots who have done a very neat transformation of the Space Invaders game look and feel (including the classic sound effects which are a joy to hear again) into a very compelling slot.

New at MrGreen Slots is the heavy metal favourite Motorhead Slot (I know Lemmy said his style was Rock N’ Roll). This NetEnt Slots powered 5 reel and 76 payline video slot plays Motörhead Music as you spin the reels.

To celebrate 20 years of online slot innovation NetEnt, the guys who brought you Starburst and Gonzos Quest, has released its NetEnt Rocks slot series. A series of rock n’ roll themed slots featuring rock n’ roll legends such as Guns N’ Roses and Jimi Handrix.
